i have a lifetime wrap around and the last thing i want to void is the motor. I have blown 3 motors in the last 3 years. My gen 1 4.7 in my 99 twice.
and i may be getting closer to that mileage if i was doing 60. I am rarely doing under 80 on the highway and hit 90+ more often then i should.
plus my route to work has a lot of lights so i'm stop and go for 20 miles a day. I take a different route home that is more highway but the ride in kills my mileage.
